Based on nearby observations and trends, lowest daytime humidities will occur overnight/in the very early morning and in the early afternoon, caused by downslope winds. There will be periods of slightly higher relative humidities in the late morning and early evening, but poor recoveries are forecasted. Humidity begins to slowly trend higher late in the week as a weather system approaches NorCal. This will also bring chances for precipitation late Saturday into early next week with potential for light snow near the burn site at higher elevations.
